What format will these documents be in? (There are certainly more than
one that support 'macros', although a certain one comes to mind as the
most suspect). You will need a program that runs on your MTA platform,
that can read that format of document and tell you if it has any macros.
I suggest you contact that vendor of the software that produces this
document type and ask either for specifications for that format (so that
you might be able to produce your own program), or a program that will
do that. You will find that they will probably laugh at you, since they
are more interested in making money than in making things work.
